IMPROVEMENT IN FASTENERS FOR THE-MEETINGRAILS OF SASHES.

Spccifisaticn forming part of Letters Patent No. 147,839, dated Fcrruary 24, 1874; application filed August 20, 187 3.

To all whom it may concern:

Be it known that I, SEWALL B. HoLBnooK, of West Medway, of the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Window-Sash Fastenings; and do hereby declare the same to be `fully described in the following specification arm being operated by the knob as occasion4 requires.

In such drawings, A and B are the parts which are to be screwed to the two sashes, the part A being xed to the lower bar of the upper of two sashes. The part B is a metallic circular segment, provided at its periphery with a raised lip, a, notched at its middle, as shown at b. The said part B or flanged segment is to be screwed down upon the top bar of the lower sash. Pivoted to the part A is the radial catch-arm G, whose rear end, formed as shown, abuts against a spring, D, arranged with it, and in the part A, in manner as rep.

' spring, f. This spring, when the arm is directly over the notch b, pulls the latch into the notch. The object of the latch is to prevent the arm from being moved laterally, either in one direction or the opposite, by a person outside of the window, by a knife or tool introduced upward between the sashes.

On taking hold of the knob, it is to be moved toward the part A, so as to d iseugage the latch from the notch, after which, by pressing the knob laterally, the arm C may be turned oft', or

out of engagement with, the segment.

I make no claim to the parts A, B, C, and j', arranged wand combined as set forth.

The lever-latch D', the knob e, and spring f, the notched segment B, the radial catch-arm C, and the part or carrier A, with its spring D, arranged, constructed, and combined as and for the purpose and to operate substantially as specified.

SEWALL B. HOLBROOK.
